To all whom it 11mg cance -n.-

. Be a. known that I, Teams A. Busine s,

of St. Louis; Missouri-,have made a new and "useful Improvement in Locomotive-Furnaces,

the iurngee for the purpose of producing. a. .more perfect combustion of'the fuel within the furnace.

It consists in a tubular-shaped or a substan and extending horizontally or of the fines backward toward the rear end at the furnace, substantially as is exhibited in the annexed drawings, inaking'part of this specification, in Which- Figure 1 is a vertical longitudinal section Fig. 2 is a vertical cross-section on the line 2 2 of Fig. 1, and Fig. 3 is a View in perspective of the tiles used in forming thefluc in question.

The same letters of reference denote the same parts. v

The locomotive-furnace A is of the usual B represents a tile, preferably slightly arched, which extends from the vicinity of the fines C rearwardly and horizontally, and sulistantially at the level ofthe top ofthe fines 0.

thereof, rearwardly and horizontally.

formed of fire-clay,

suhsiantiall y D represents a tile extending from the vicinity of tl1e 'flues, at the level of the bottom tile, which may be made in one or more parts, is preferably concave in its upper surlaccmnd with the side wails ofthe furnace and the upper tile, 13, which alsomay be made in one or more pieces, forms the tubular flue in question.

Two important advantages accrue from this improvement: The tiles become more highly heated than the furnace-walls, aud smoke from the fuel is, in consequence, more thoroughly consumed. At the same time the lines (J remain in full View, and can be reached for cleaning or repair without having to move the tiles.

Air can be admitted to the furnace through openings E in the rear wall of the furnace.

The tiles can he supported in any desirable" O. D. MOODY, B. F. REX.
